     multi method ords(Str:D:) returns Positional
 
-Returns a list of codepoint numbers, one for the base character of each
-grapheme in the string.
+Returns a list of Unicode codepoint numbers that describe the codepoints making up the string.
 
 Example:
 
     "aå«".ords; # (97 229 171)
 
+Strings are represented as graphemes. If a character in the string is represented by multiple
+codepoints, then all of those codepoints will appear in the result of C<ords>. Therefore, the
+number of elements in the result may not always be equal to L<chars>, but will be equal to
+L<codes>.
+
+The codepoints returned will represent the string in L<NFC>. See the L<NFD>, L<NFKC>, and
+C<NFKD> methods if other forms are required.
